WILLIAM E. RAMAGE AND HENRY n. SHAW, 0F ADAMS, MASSACHUSETTS, Assrenons T0 BERKSHIRE HILLS PAPER COMPANY, or DAMS, MASSACHUSETTS.

PAPER-GEoovING MACHINE.

To all whom it may concern:

Be'it known tl at we, lVILLrAM E. RAMAGE and HEZNRY D. t HAW, citizens of the United States, residing at Adams, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvewhich the following is a specification. Our invention relates. to lmprovements in paper grooving machines, and has for its object the provision 'of simple and eflicient mechanism for forming grooves in certain port ons of the paper or parchment to render 'such portions more flexible and easy to handle. In books which are handled a great deal such as loose-leaf ledgers and the like, the leaves along the binding edge or hinge portion are subject to a great deal'of strain finally tear, but .we are able with our im provements to render the leaves more flexible along their hinge edge without sacrificing the strength of the leaf, so that the leaves may be handled with greater ease and less strain, and will in fact be more durable and last the longer for such treatment.

Another object of our invention is to provide practical means for cleaning, smoothing and burnishing the grooved portion of the paper so that such grooved portion while being more flexible than the rest of the sheet,

' shall present the same surface and appear ance and possess substantially the same strength and wearing qualityas the'balance of the sheet, and also to provide means for removing the loose fibers or cuttings during the grooving operation. Z

A further object of the invention is the provision of paper grooving. mechanism which shall be adjustable in its construction so that the groove may beformed of the desired depth, width' and shape, and one or a number of grooves may be cut at will and uponany portion of the paper..

A final object of our invention is to produce grooving mechanism which-shall be practical and efii'cient in every particular and with the above objects in view, our in vention comprises an adjustable platen or support for the paper, one or=more cutters journaled to cooperate with the platen ,to

form grooves in the paper, and means for cleaning the grooves of all loose fibersand to leave such grooved portions with a smooth surface.

the line 4 -4 of Fig. 3. Fig. 5, is a broken attached direct to the paper making ma:

chine so that the web of paper is acted upon during the process -of its. manufacture and thus the grooved paper may be produced at. as rapid a rate as the plain paper itself, I but of course it will be understoodthat our grooving machine may be operated as such entirely independent of a paper making or other machine. It has been found very practicable to introduce our'device incorrnection with paper machines: of the Four;

drinier type and it is illustrated in such-con.

nection in the drawings herewith.

Referring now to v the drawings by num'eral; Thenumeral 1, designates the frame of a paper making machine ,and'2, the drier;

rolls journaled therein.,,The web of paper;

3, is caused to pass overthese-drier rolls in.

the course of its manufacture, and the guide rolls 4, serve as guiding means ,for the web. We find that it is preferable to. groove the paper while it is in a practically dry condition and before it has been sized, and we therefore prefer to locate the grooving' mechanism upon the pa er machine inyad vance of the last drier r0 1, 1t being shown in such posltion 1n the accompan ng drawings, but of course the particu arlocation- 'of the device is optional and may be gov:

erned by different requirements.

The grooving machine comprises a frame inc 5, which is suitablymountedupon the paper.

machine or otherwise, and at the ends of this frame are mounted the gulde rolls 6,

over whichthe web of paper travels.

horizontal cross bar 7, is arranged in the forward portion of the frame in rear of the first guide roll which is provided with a raised ledge ortrackway 8, along its forward upper edge and a guide rod .9, is mounted in brackets 1'0,-'upon the cross bar, which cross bar, may be of inverted channel iron type as shown or, other suitable formation. A carriage 11, is supported upon the cross bar, t e carriage having a rearward sleeve extension 12, slidably engaged upon the guide rod 9, and an eccentric cam 13, 1s

pivoted in the forward portidn of the car riage which engages the trackway and supports the forward edge of the carriage.

The cam is provided with a weighted handle' 14, which by reason of its weight causes the cam to normally hold the forward edge of the carriage in uplifted position. A. stop or abutment 15, is formed on the cam handle ,to engage the edge of the track'way'and a set screw 16, is carried by the sleeve to engage the guide rod and hold the carriage in adjusted position upon the guide rod. Along the upper forward edge ofthe carriage is arranged a box 17, in which are slidably confined the pair of oppositely disposed Wedge blocks 18, there being thumb screws 19, j ournaled in' the opposite ends of the box and engaging the wedges to regulate the positionof the wedges. A platen or sup porting block 20, is confined 1n the upper portion of the box, the lower edges of the platen being oppositely inclined toward the ends and such inclined portions resting upon the Wedges, so that by operating the thumb screws to withdraw or extend the wedges,

overhai'iging beveled edges 26, to interlock with the inclined edges of the rib on the cutter head, so that a dove-tail joint is thus provided between the cutter head and the support therefor to allow of the cutter head being adjusted laterally, and a set screw serves to hold the cutter head in adjusted position. The cutter head is provided with a pair of outstanding journal brackets 28, in which is journaled the horizontal cutter shaft 29, and the pulley 30, fined on said shaftmay be connected by belt or; otherwise to rotate the shaft. -The cutters consist of one or more disks 81, preferably of emery or the like abrasive material, the disks when there are more than one disk), being held in the proper spaced relation by the spacing rings or washers 32, the disks being clamped between the annular flanges 33, and held by the securing nut In this way, by loosening the clamping nut on the end of the shaft, any numberof cutters may be mounted thereon in any desired spaced relation, so that either one or a number of parallel grooves may be cut in the paper. The cutters are preferably rotated at a high rate of speed and in a direction opposite to the travel of the paper. The cutters are also adjustable in a verticalplane in this manner; the cutter head supporting bar has angular ends 85,

' in which are mounted three or more bolts 36,

which work through vertically arranged slots 37, formed in the frame, the nuts 38, on the ends of these bolts serving to secure 'he supporting bar when adjusted to the proper height. Set screws 39, are engaged in the ends of the cutter head support and bear on the stationary ledge 40, so that by adjusting these set screws the cutter head support may be raised or lowered at will.

Vertical guideways all, are formed near the rearportion of the frame and in said guidemiys are slidably confined the journal brackets 42. The brackets are slotted longitudinally at 43, to receive the stationary securing bolts 44, and the nuts 45, on said bolts clamp the journal brackets in theiradjusted position. Adjustment screws 46, mounted in the lower ends ofthe brackets engage the stationary lugs 47, and serve for raising and lowering the brackets. A brush shaft 48, is journaled in the adjustable journal brackets, the shaft passing through enlarged openings 49, in the sides of the frame to. allow clearance for the adjustment of the shaft. A rotary brush 50 is mounted on the shaft and this brush is preferably long enough to reach across the web of paper and clean the entire surface thereof, including the grooved portions.

Some nieans has to be provided for disposing of the cuttings and loose fibers created by the cutter wheels as otherwise these fine particles or dust would get into the animal sizing and would stick to the wet portion of the paper, thereby spoiling the process. To this end, a pneumatic suction apparatus is provided in the shape of a main collector pipe 53, which is in connection with a suitable exhaustfan or blower 54, and a dust collector or receiver 55. A hood 56,is placed over the brush and is connected by tributary or branch pipes 57, with the main collector pipe, the branch pipes preferably being placed on a. slant-in the direction of the exhaust current as shown. Hoods 58, are also placed over each of the cutters and these hoods are connected to the main collector pipeby the tributary pipes 59. These last named tributary pipes are flexible in order to allow adjustment of the hoodswith respect to the cutters,and these flexible pipes may consist ofa canvas or fabric covering 60, which may be held expanded by means of internal rings not shown, or other forms of flexible piping may be used. Thus suctionis produced 'in the collector pipes by meansl'of. a fan or. otherv air-exhausting apparatus and most of the dust is carried away directly from beneath the, cutters, andthe balance of the: dust is taken up from underneath and around. the brush, so-that the paper is left perfectly clean.

The operation of .the'machine is as follows: Whenused'in connection with a paper making machine, the" pa er, is ledup from the last or near thelastl. rier roll when 'in a dry or almost dry condition, over the guide roll at the front .end'lof the'grooving ma chine and between the' 'adjustable platen and the cutters. The cutters bein direction opposite to the travel of the paper rotated in. a

make a smooth cl'eancutin the surface of the paper and the depth of the out may be regulated" by. adjusting the platen. By.

using any numberof cutters and of any desired conformation, the number-andshape of the groovesmay begoverned to suit differient conditions. The cutters may be rendere'd inoperative by simply lifting the cam on the platen carriage, thereby lowering the platen and thepaper simported thereby from contact with the cutters.

As shown in the top plan view Fig.2, the cutters may be operated infsi ng e sets or ainumber, of

'cutter setsmay'be mounted onthe same shaft. The arrangement, shown in this figureis for groovin'g an extra wide sheet of paper which is afterward-to be divided into' three strips, the strips having a hinge portion along each edge; The paper after leaving the cutters then passes under the burnishingbrushw ich. is also rotated ina directioirop'positetothe travel of the paper.

*Qilhis brush cleans the grooved portions of all loosegfibers which might have escaped the first set of dust collectors, and as it is rotated at a high rate of speed, it leaves the grooves with ahard smooth finish equalto the rest of the surface of the, paper. A platen may be provided for the support of the paper beneath the brushes if desirable. The brushes may be operated by a pulley 52, on the end of the brush shaft or other driving connections may be employed. The

paper after leaving the groovingmachine is then passed through the slitters or rotary knives which cut it into the proper sized strips, it is then sized, calendered, finished and dried in a drying loft or otherwise. In this Way, the grooves receive a coat-of sizing and are afterward finished in the same -manner as the plain portion of the paper,

the sheet, still possess practically thesame strength and smooth finish as the rest of the sheet, and on account of the sizing 1n the grooves, and the fact that in calendering, the sheet proper is pressed to aboutone half 'its original thickness or practically to' the thickness of the grooves, the grooved portion is of substantially the same thickness as the sheet proper.

l/Ve have found it advisable under certain conditions to support the paper from the sides while being grooved, rather than from underneath, and in Fig. ,5, is shown a form Way. Here the .upper edge of' the platen is formed with a series of grooves 62 therein, of slightly greater. width than the cutters, there being ribs 63, provided to support the paper between the cutters. Vhile only two forms of paper supports have been, illustrated, other forms may be employed to suit different conditions and requirements rial than steel. As all the parts of the machine are fad-r of platen for supporting the paper in this and the platens may be made of other matejustable, themultiplicity, arrangement and sha e of the grooves may be varied to suit di erent conditions and. requirements, and

while illustrated as applied to a paper makin a thorough and eminently satisfactory manner.
